What's the best way to implement user activity in symfony 2 ?
And how to do it ?
I know there is the event system of symfony 2. Maybe I should trigger an event ?
And is it wise to update on every page request or are there other (better) ways to update user activity ?
Good way to track user requests (and possibly their activity) is to listen to kernel.request event:
Listener class:
namespace Acme\YourBundle\EventListener;
use Symfony\Component\HttpKernel\Event\GetResponseEvent;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\DependencyInjection\ContainerInterface;
class RequestListener
{
/**
* Container
*
* @var ContainerInterface
*/
protected $container;
/**
* Listener constructor
*
* @param ContainerInterface $container
*/
public function __construct(ContainerInterface $container)
{
$this->container = $container;
}
/**
* kernel.request Event
*
* @param GetResponseEvent $event
*/
public function onKernelRequest(GetResponseEvent $event)
{
$request = $event->getRequest();
// Here you can intercept all HTTP requests, and through $container get access to user information
}
}
Configuration for the listener:
<container xmlns="http://symfony.com/schema/dic/services"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://symfony.com/schema/dic/services http://symfony.com/schema/dic/services/services-1.0.xsd">
<parameters>
<parameter key="acme.request_listener.class">Acme\YourBundle\EventListener\RequestListener</parameter>
</parameters>
<services>
<service id="acme.request_listener" class="%acme.request_listener.class%">
<tag name="kernel.event_listener" event="kernel.request" method="onKernelRequest" />
<argument type="service" id="service_container" />
</service>
</services>
</container>
You can get more info on this topic in the official Symfony documentation:
public function onKernelController(FilterControllerEvent $event)
{
$controller = $event->getController();
if ($controller[0] instanceof Controller and (!strpos( get_class($controller[0]), 'App\FrontendBundle')===false) ) {
}
}
